Description
Technical Field
The invention relates to the technical field of ceramic preparation, in particular to a wear-resistant smooth flowing white glaze ceramic product and a preparation method thereof.
Background
The white glaze appears in the Han dynasty earliest and is more than 400 years later than the celadon, the white glaze porcelain begins to be bluish white, and because the iron content in the porcelain is higher than 1% and is cyan and less than 1% is the white porcelain, the Chinese white porcelain undergoes the development process of the celadon, the egg white glaze, the sweet white glaze, the ivory white and the white glaze. In China, the places of production of white porcelain historically include Dehua white porcelain, fixed kiln white porcelain, criminal kiln white porcelain and the like.
The iron content in the porcelain glaze is reduced to below 0.75 percent, and the porcelain glaze is applied to white porcelain body and put into a kiln to be fired at high temperature to generate white glaze. Strictly speaking, a white glaze is a colorless transparent glaze, not a white glaze. The white glaze is one of the traditional glaze colors of the porcelain, the real white glaze is milky opaque glaze, and the glaze is invented recently. Only the first generation of Yuan Shufu glaze in ancient China is devitrified, other white glazes are not white glazes, the white glaze firing process is more complicated than the green glaze, the occurrence time is later than that of the green glaze, general porcelain clay and glaze materials contain a plurality of iron oxides more or less, and the porcelain clay and glaze materials are inevitably in cyan with different depths after being fired. If the content of the iron element in the glaze is less than 0.75 percent, the white glaze is obtained after firing.
The ceramic products are also rubbed with each other frequently in the carrying and cleaning processes, various scratches are formed on the glaze surface, the appearance of the domestic ceramics is directly influenced, and the service life of the domestic ceramics is shortened. In the process of realizing the conversion from the large-scale type to the benefit type of the domestic ceramics, the glaze quality problem becomes the biggest obstacle for restricting the further improvement of the quality of the ceramic products in China. At present, the performance research of the glaze of the daily ceramic mainly focuses on the aspects of how to improve the appearance and the appreciation of the glaze, such as glossiness and chroma, and the like, the design of the ceramic glaze layer, the color and the like, and few researches are carried out on the wear resistance of the daily ceramic glaze.

The invention has the beneficial effects that:
(1) the titanium dioxide contained in the raw materials of the glaze obviously improves the brightness and whiteness of the glaze layer, and the addition of the silicon dioxide can effectively increase the transparency of the glaze, optimize the physical and chemical properties of the glaze and enable the glaze to present white and moist color. The boron frit and the barium carbonate which are used as fluxing agents can effectively reduce the temperature required by sintering glaze, are beneficial to improving the wear resistance of the glaze and save the cost.
(2) In the wear-resisting agent adopted in the invention, calcium oxide is a divalent network exosome oxide, which is beneficial to generating free oxygen at high temperature of glaze, destroying network structure, reducing melt viscosity and promoting glaze melting, and is a good high-temperature flux component. Corundum and zirconium silicate which are used as hard crystals can obviously improve the wear resistance and hardness of the glaze, wherein the corundum mainly comprises alumina, and during the glaze melting process, the alumina can capture free oxygen to form tetrahedrons to enter a silica-oxygen network and can also be combined with alkaline oxide, so that the glass network structure is strengthened. The chemical stability, hardness and mechanical strength of the glaze can be improved by increasing the content of the alumina.
